TAN K-HEATER.

SPECIFICATION forming part of Letters Patent No. 418,744, dated January7, 1890.

Application tiled July 2, 1889. Serial No. 316,361. (No model.)

` city of Red Oak, in the county of Montgomery and State of Iowa, haveinvented a new and useful Tank-Heater, of which the following is aspecification.

My invention relates to improvements in tank-heaters; and the objects ofmy improvements are to provide a tank-heater adapted to be immersed inthe Water of tanks and reservoirs, and which will prevent the watercontained therein from freezing in the coldest Weather, and which willkeep the water during the Winter at a suitable temperature to be drankby cattle and other animals. I attain these objects by the deviceillustrated in the accompanying drawings, in which- Figure 1 is aperspective view of the tankheater. Fig. 2 is a perspective view of thetank-heater, having a portion of its case broken away, so as to shovsTthe inside of the heater. Fig. 3 is a detailed vertical sectional viewtaken on line :t at, Fig. 2, of the reservoir of the heater.

Similar letters referto similarparts throughout the several views.

In the accompanying drawings, A designates the case of the tank-heater,which is open at its bottom and closed at its top by v j means of thecover n, and which is provided at its base with the outwardly-extendingcircular ange t. Y

B is a lamp provided atit-s base with the circular flange g, the outeredge of which projects outward flush with the outer edge of the ange t.

L is a rubber disk or packing that is located between the flanges t andg.

P is a weight that is secured to the bottom of the lamp, and is employedto hold the tank-heater down in the water of the tank. The metalliclamp-chimney c has an aperture m, which is covered with glass.

D is a tubeor Hue, the lower end of which passes snugly through anaperture in the top or cover n of the case A and opens into the heater.

F F are bent tubes employed to supply the lamp with air, the lower endsof which are bent and pass snugly through apertures in the case A andopen into the heater. They are secured to the cover n by means of theloops a.

C is the circular-shaped reservoir of the tank-heater, which is closedupon all sides and has the diameter of its upper portion reduced,forming the hollow upwardly-extending projection K. The reservoir C ismade of smaller diameter than the case A and is held in a properposition above the lamp-chimney e by means of the four tubes I-I, theinner ends of which pass snugly through the sides of the projection Kand open into the upper reduced portion of the reservoir C, and theirouter ends pass snugly through apertures in the case A and projectbeyond the case.

I is a bent tube, which opens at its upper end into the reservoir O. Itextends outward from the reservoir C, and passes snuglyV through thecase A. Thence it extends downward upon the outside of the case-A nearlyto the base of the heater. One or more of these tubes can be used. l Eis a hood, which is secured to the top of the flue D by means of thesleeve w. This hood is employed to keep the upper ends of the tubes F Fand D free from snow and ice.

G are hooks, which are hinged at their lower ends to the flange g of'the lamp, and which engage at their upper hooked ends with theperforated lugs fi, which are secured to the case A. Several of thesehooks can be used to sec-ure the lamp to the case A. By disengaging thehooks G from the lugs 'L' the lamp can be withdrawn from the case A andfilled and trimmed.

The rubber disk L makes a Water-tight Sev joint between the flanges tandg. The aperture d is tightly closed by a glass cover, and When the lampis burning the light is reiiected through the aperture, so that in thenight-time a person can determine Whether or not the lamp is burningwithout withdrawing it from the case A.

ows into the reservoir C through the tube I. Thus the entire Water ofthe tank circulates through the reservoir C and becomes warm.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

The herein-described tank-heater, consisting of the case A, providedwith the aperture d, having a transparent covering, the reservoir C,located within the case, the Hue D, the air-tubes F, the lower ends ofwhich open into the case and which extend upward outside of the case andare bent in such a manner as to extend upward along the flue, so thatthe hood E will reiect the heat that es- KENNETH MCLENNAN.
